UPDATE 11 a.m. EST: The Pope recently arrived at the World Trade Center, where he said a prayer at the 9/11 Memorial reflecting pool. He also spoke with family members of some who died on September 11.

Original story starts here:

Pope Francis arrived in Washington, D.C., for his first visit to the United States on Tuesday afternoon around 4 o'clock, where he was met by President Obama and Vice President Biden at Andrews Air Force Base.

The United States Conference of Catholic Bishops will be live-streaming all of the Pope's televised activities here, though many news networks will be doing the same at his various stops in Washington, New York City and Philadelphia. (Here is ABC-New York's live-streaming landing page, for example.)
